%s caracter class

[Maxime Chupin <mc@...>]

Hi,

I don't really inderstand how work %s. For example, I wrote this code (probabely, it is not a a beautiful code :-)) :

--------------------------------------------------------
function split(chaine,motif)
   local tableau={};
   local num1,num2;
   local chaineloc=chaine;
   num1,num2=string.find(chaineloc,motif);
   if num1==nil and num2==nil then
      tableau=chaineloc;
   else
      local i=1;
      while num1~=nil and num2~=nil do
     tableau[i]=string.sub(chaineloc,1, num1);
     chaineloc=string.sub(chaineloc,num2+1);
     num1,num2=string.find(chaineloc,motif);
     i=i+1;
      end
      if chaineloc~="" then
     tableau[i]=chaineloc;
      end
   end
   return tableau;
end


t="cou   cou2 co\nu3   cou4    ";
a={};
a=split(t,"(%s+)");
print("1 : "..a[1]);
print("2 : "..a[2]);
print("3 : "..a[3]);
print("4 : "..a[4]);
print("5 : "..a[5]);
-------------------------------------------------------------   

And this produce :
1 : cou 
2 : cou2 
3 : co

4 : u3 
5 : cou4 

I wanted:
1 : cou
2 : cou2
3 : co
u3
4 : cou4

Why does not it  work as I want ? %s is not only for the space ?
Thanks.
Best regards,
